The phone interview consisted of two parts. 1) Coding and 2) Questions about area of your choice 1) First, the interviewer asked me to choose two languages. I chose Matlab and C++. Matlab questions were somewhat easy, however I had some hard time during C++ questions. 2) For the technical area, I chose signal processing. Since I have EE background, these type of questions were easy.

There were three phases for recruiting procedures. The first stage was a brief and relaxing conversation, the second stage was about technical things and hiring manager asked several questions in the third stage.
